Description

Die Neuerung bezieht sich auf eine elektrische Kontaktklammer entsprechend dem Oberbegriff des Anspruches 1.The innovation relates to an electrical contact clip according to the preamble of claim 1.

In den bisher bekannten Anwendungsfällen, wo es das Problem höherer Stromaufnahme nur bis maximal 16 A gab, hat man das entweder mit Kontaktelementen mit einliegender Stahlfeder gelöst oder aber entsprechend ausgebildete Kontaktelemente nach dem Einsetzen in ein Trägerteil, z.B. eine gedruckte Schaltungskarte, dann mit den Leiterbahnen des Trägerteiles z.B. durch Verlöten kontaktsicher und nicht lösbar verbunden, um ein Abrutschen der Kontaktelemente von den Leiterbahnen zu verhindern.In the previously known applications, where there was only the problem of higher current consumption up to a maximum of 16 A, this was either solved with contact elements with an inserted steel spring or else appropriately designed contact elements after insertion into a carrier part, e.g. a printed circuit board, then with the conductor tracks of the carrier part e.g. connected by soldering in a contact-safe and non-detachable manner to prevent the contact elements from slipping off the conductor tracks.

Es sind auch Ausführungen solcher Kontaktelemente bekannt, die an der der Stecköffnung der Elemente gegenüberliegenden Seite zusätzlich Ansätze aufweisen, die mit den Leiterbahnen der Trägerteile zur Herstellung und Sicherung der elektrischen Verbindung der Elemente mit dem Trägerteil vernietet werden.Designs of such contact elements are also known which additionally have lugs on the side opposite the plug-in opening of the elements, which are riveted to the conductor tracks of the carrier parts in order to produce and secure the electrical connection of the elements to the carrier part.

Von der Herstellung wie auch der zuverlässigen Kontaktierung sind diese Ausführungen jedoch für Zentralelektriken bei Stromaufnahmen größer 16 A bis 45 A zu aufwendig und hinsichtlich der gelöteten oder genieteten Verbindungen elektrisch dann nicht unbedingt zuverlässig.From the production as well as the reliable contacting, however, these designs are too complex for central electronics with current consumption greater than 16 A to 45 A and are not necessarily electrically reliable with regard to the soldered or riveted connections.

Der Neuerung liegt die Aufgabe zugrunde, eine elektrische Kontaktklammer für Zentralelektriken im Automobilbau oder auch in der Energietechnik, z.B. für Stromschienen bis mindestens 45 A Stromaufnahme, zu schaffen, die als Gabelfeder ausgebildet in ein Trägerteil, z.B. in eine metallene Leiterbahn oder eine durchkontaktierte gedruckte Schaltungskarte unter Vorspannung federnd eingesetzt, mit dem Trägerteil dann kontaktsicher verbunden ist und die sowohl einfach wie auch preisgünstig herstellbar ist.The innovation is based on the task of creating an electrical contact clip for central electrical systems in automobile construction or also in energy technology, for example for busbars with a current consumption of at least 45 A, which is designed as a fork spring in a carrier part, for example in a metal conductor track or a plated-through printed circuit card under spring tension, then connected to the carrier part in a contact-safe manner and which is both simple and inexpensive to manufacture.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß die Kontaktklammer vom Scheitelpunkt der U-förmig gebogenen Jochfläche ausgehend in einem bestimmten Abstand beidseitig der parallel verlaufenden Federarme Ausnehmungen mit einem öffnungsmaß aufweist, das etwa gleich der Stärke des Trägerteiles ist.According to the innovation, this object is achieved in that the contact clip, starting from the apex of the U-shaped curved yoke surface, has recesses with an opening dimension on both sides of the parallel spring arm with an opening dimension that is approximately equal to the thickness of the carrier part.

In weiterer vorteilhafter Ausgestaltung der Neuerung ist die Kontaktklammer so ausgebildet, daß sie auch wahlweise um 90° versetzt in das Trägerteil einsetzbar ist.In a further advantageous embodiment of the innovation, the contact clip is designed in such a way that it can also optionally be inserted into the carrier part offset by 90 °.

Embodiments of the innovation are described below with reference to the drawings. It shows
  • Fig. 1 is a partially cut schematic diagram of the contact clip, inserted into a carrier part, in view.
  • Fig. 2 contact clip and carrier part in side view.
  • Fig. 3 contact clip and carrier part in plan view.

  • Fig. 5 used in carrier parts contact clips in perspective.

Die in den Figuren 1 - 3 gezeigte Kontaktklammer 1 ist aus elastischem elektrisch leitendem Material einstückig gestanzt, wobei der Grundkörper der Klammer 1 im Grundriß rechteckig gestaltet ist. Der Grundkörper ist entsprechend Fig. 2 um seine Mittelachse X - X gleichmäßig U-förmig mit Radius R zur Jochfläche 2 gebogen, von wo aus dann zuerst parallel verlaufend sich Federarme 3 erstrecken, die etwa im Abstand a1 ab dem Scheitelpunkt A der Jochfläche abgewinkelt gleichmäßig nach innen zueinander und dann etwa im Abstand a2 ab dem Scheitelpunkt A abgewinkelt gleichmäßig nach außen auseinander verlaufen, derart, daß sich im Punkt B der Steckbereich c bildet.The contact clip 1 shown in FIGS. 1-3 is stamped in one piece from elastic, electrically conductive material, the base body of the clip 1 being rectangular in plan. The base body is bent according to FIG. 2 about its central axis X - X uniformly U-shaped with radius R to the yoke surface 2, from which spring arms 3 then extend in a first parallel manner, which angled approximately at a distance a 1 from the apex A of the yoke surface run evenly inwards to each other and then angled approximately at a distance a 2 from the apex A evenly outwards in such a way that the plug-in area c forms at point B.

Wie der Fig. 1 zu entnehmen ist, weisen die Federarme 3 innerhalb ihres parallel verlaufenden Bereiches Ausnehmungen auf, mit denen die Kontaktklammer 1 nach dem Einsetzen in die Öffnung E des Trägerteiles 4, dieses dann im Bereich der Ausnehmungen übergreift. Die Ausnehmungen sind so gestaltet, daß sie, ausgehend vom Scheitelpunkt A der Jochfläche 2 im Abstand a3 beginnend, ein Öffnungsmaß h aufweisen, das sich in Richtung Steckbereich c erstreckt und etwa gleich der Stärke s des Trägerteiles 4 ist und ausgehend von den Außenkanten der Breite b der Klammer 1 beidseitig eine Tiefe t aufweisen.As can be seen from FIG. 1, the spring arms 3 have recesses within their parallel region, with which the contact clip 1, after being inserted into the opening E of the carrier part 4, then engages over this in the region of the recesses. The recesses are designed in such a way that, starting from the apex A of the yoke surface 2 at a distance a 3 , they have an opening dimension h which extends in the direction of the plug-in area c and is approximately equal to the thickness s of the carrier part 4 and starting from the outer edges of the Width b of the clamp 1 has a depth t on both sides.

Fig. 3 zeigt in Draufsicht die Kontaktklammer 1 in Trägerteil 4 eingesetzt, wobei in einem Teilausschnitt C eine Abschrägung D der quadratischen Öffnung E des Trägerteiles 4 sichtbar ist. Diese Abschrägung D ist gleichmäßig an den Ecken der Öffnung E des Trägerteiles 4 vorgesehen und so ausgelegt, daß im Punkt F der Abschrägung D die Kontaktklammer 1 nach dem Einsetzen dann in der Öffnung E des Trägerteiles 4 fixiert ist.FIG. 3 shows a top view of the contact clip 1 inserted in the carrier part 4, a bevel D of the square opening E of the carrier part 4 being visible in a partial cutout C. This bevel D is evenly provided at the corners of the opening E of the support part 4 and is designed so that the point F of the bevel D the contact clip 1 is then fixed in the opening E of the support part 4 after insertion.

Fig. 4 zeigt in perspektivischer Darstellung eine in ein Trägerteil 4 eingesetzte Kontaktklammer 1 und in Fig. 5 ist in Perspektive eine Mehrzahl von Trägerteilen 4 sowohl mit freien Öffnungen E wie mit in diese eingesetzte Kontaktklammern 1 dargestellt.FIG. 4 shows a perspective view of a contact clip 1 inserted into a carrier part 4 and in FIG. 5 a perspective view shows a plurality of carrier parts 4 both with free openings E and with contact clips 1 inserted therein.
